Allow subscribing to a serial BEFORE it's indexed
When I find a new web comic I want to read, my immediate impulse is check if it's on Serialist. If it's not, then I add it to Serialist. Unfortunately, I can't subscribe to the new serial until Serialist has indexed it. Usually I wind up forgetting to subscribe.
So it would be nice if, at the point of adding a new serial, I could subscribe to it.
There was a time when this worked. That time will come again.
